COMBUSTION TURBINE.

Application filed June 27, 1927. Serial No. 201,784. I

The present invention relates to combustion turbine and has for itsprime Object to provide a highly eflicient structure including a blockwith a shaft rotatable therein and a rotor keyed thereto, the rotorhaving vanes incorporatedtherein and means being'provided in the blockfor exploding gas and causing the exploding gas to impinge and expandagainst the vanes to set up. rotary motion in the shaft through therotor.

Another important object of the invention resides in the provision ofvalve means in the block structure for controlling the intake andexhaust of the gases at the proper timed intervals so as to obtain themaximum power with economy.

A still further very important object of the invention resides in theconstruction of a combustion turbine'of this nature which iscomparatively simple in its construction, compact, has its partsconveniently arranged, and is otherwise well adapted to the purpose forwhich it is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

Figure 6 is a detail sectional view taken substantially on the line 6-6of Figure 5,

Figure 7 is an enlarged detail section taken substantially on the lme7-7 of Figure 4, v

Figule 8 is a transverse vertical section taken substantially on theline' 88 of Figure 1.

Figure 9 is a detail sectional view showing particularly one of therollers for the valve plates and the mounting thereof.

Referring to the drawings in detail it will I ends of the bearing 7. Awater jacketed plate 10 is formed at one end of the bearing and has arim 11 at the periphery thereof. This nm 11 is provided with a pluralityof firing chambers 12 and the plate 10 is provided with passages 13 oneleading from each firing chamber 12. The rim 11 is water jacketed aslndlcated at 14. A water jacketed casing 15 is bolted or otherwisesecured as at 16 to the rim 11, and houses the rotor R. The wall 16 ofthe casing is jacketed and provided with openings 17 There are the samenumber of openings 17 as there are passages 13 and firlng chambers 12.An exhaust manifold 18 has branches 19 leading from the openlugs 17 toan exhaust pipe 20. The shaft 5 is journaled through the wall 16 and theexhaust manifold. This exhaust manifold is jacketed and in communicationwith the jacketed structure of the wall 16. This exhaust manifold isfurther provided with a gear casing 21 in which are journaled shafts 22and 23. The shaft 22 has thereon inside the casing 21 a pinion 24meshing with the gear 25 on the end of the shaft 5. A gear 26 isdisposed on the end of the shaft 23 in the housing or casing 21 andmeshes with the gear 25.

The rim 11 of the .block structure B is provided with a plurality ofintake passages 28, one leading into each firing chamber 12 through avalve seat 29. .Poppet valves 30 are seatable on the seat 29 and havestems 30' slidable through bearings 31 formed interiorly of the rim 11.Springs 32 are disposed about the valve stems 30' and normally tatableabout" the bearing 7, anti-friction bearings 37 and 38 being interposedtherebetween. This annulus-36 is provided at one end with an internalgear 39 with which meshes a gear 40 on a shaft 41. This shaft 41 isjournaled through a head 42 and a bearing 43. The bearing 43 is fixed tothe bearing 7. Thehead 42 is disposed about the bearing 7 and is boltedor otherwise secured 'as at 44 to the rim 11. The front end of the shaft5 has a gear 46 thereon which meshes with the gear 47 on the front endof the shaft 41 and thus when the'shaft 5 is rotating the annulus 36 isrotating in opposite direction thereto. A casing 48 houses the gears 46and 47 and is attached to the forward end of the bearing 7 by a bolt 49or in any other suitable manner and to the head 42 by the bolt 44heretofore referred to. A socket 50 is formed to project from the casingand the shaft 5 has a crank receiving extension 51 so that a crank 52may be inserted in the socket to engage the extension 51 for crankingthe turbine.

Spark plugs 52 are'mounted in the rim 11 to extend into the firingchambers 12 and will be suitably wired with a distributor 53 actuated bythe shafts 41. An annular cam member 54 is formed on the annulus 36 andhas a single protrusion 55. The rollers 34 ride on the cam 54 and whenthey engage the protrusion 55, the intake valves 30 are opened as willbe clearly apparent. An intake manifold 56 has branches 57 one leadingto each intake passage 28 so that combustible gas under pressure may befed to the explosive chambers 12 when the valves 30 are opened.

The valve plates 59 are slidably mounted across the passages 13 by meansof guides 60.

Plates 61 radiate inwardly from the rim 11, one adjacent each valveplate 59 and have openings 62 through which extend bolts 64 adjustablyanchored on lugs 65 by means of nuts 66. Rollers 67 are mounted at theends of the bolts 64 to bear against the valve plates 59. Each valveplate 59 has an extension 69 with a roller 70 journaled on the extremitythereof and extended into a channel 71 of a general annular formationbut having an inwardly directed section 72 for opening the exhaust valveplates 59. This groove 70 is formed in a flange 7 3 provided" on theannu- The rotor It comprises a hub 74 keyed to the shaft 5 at 6, a rim75 and a. plurality of vanes 76 which extend tangentially from the hub74 to the rim 75 and are curved longitudinally and transversely as willbe apparent from an inspection of Figures 5 and 6.

From the above detailed description it is thought that the operation ofthe turbine may now be followed. The turbine is cranked by hand asexplained with the hand crank 52 or by any suitable starting mechanismsuch as are now commonly in use operating through the shaft 22. As theshaft 5 revolves, referring to Fi res 2, 4, 5 and 8, in acounterclockwise irection the rotor 36 is revolving in a clockwisedirection, and at regular prehaust pipe 20. The shaft 23 may be used asa power shaft for operating the desired mechanism or machine.

It is thou ht that the construction, operation, and a vantages ofthisturbine willnow be clearly understood by those skilled in this artwithout a more detailed description thereof. The present embodiment ofthe invention has been disclosed indetail merely by way of example sincein actual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described the invention, What I claim as new and desire tosecure by Letters Patent is 1. In a combustion turbine, a blockcomprising a cylindrical bearing and a plate at one end thereof formedwith a rim extending about the bearin in spaced relation thereto,
